Just got back from vegas and redeemed a few MyVegas offers. I do not think you trigger a visit if you use them. I had 2 comp buffets for Luxor and so did my brother. 1 day we used his comp but he didnt have his card, they had a special MyVegas line set up at the Luxor but he didnt have the ability to print a new card. He said all he needed was an mlife number and it didnt matter whos. So I gave him mine, he filled it out on a piece of paper and off we went. The next day we went back with my offer and my card and it was the same thing. Did the Delights at the Signature with my brothers offer. Online it says breakfast or something. Turns out its a $50.00 comp. Great deal! This time he had a copy of his card so they ran it through on his. But again they said it didnt matter. The only pisser on the Delights comp is how far away it actually is from the Mlife booth to redeem it. By the time you get there you are practically behind Planet Hollywood! Its a long haul for sure.
